a furnace F to heat the boiler und generate gas under pressure troni the fuel therein, an. engine E, means tor eonveyiiig the generated gas under pressure. fron: the boiler B to the engine E, and means for Conducting' the exhaust from the engine to the tur" nace l? to be consumed by the latter. In niost eas-es, a supply tank 'il will be provided for the liquid fuel, un injector l will be used to supply the boiler il with fuel :troni said tank l", und ineans will be used tor eondueting'part ot' the exhaust into the supply tank and condensing the saine for further use.

Although the boiler B Could be of any preferred construction, it preferably eonof an oiiiter shell 1, an inner shell 2, a pressure dome or the like a` retort il heated by the 'furnace-` ll, and a coil rising troni said retort in the shell 2 and discharging into the dome Thespaee G between the two shells l and is adapted to contain the liquid fuel troni Which the is to be generated, and by reference to 3, it will be observed that `the retort l communicates with this space, so that the liquid will be heated in the retort -il and eoil 5, being diseharged troni the latter into the bottoni of the deine 3 from which it will circulate through nipples 7 and return to the space l. ln traveling in this manner, the liquid fuel is highlyT heated and caused to give oli gas `which collects under pressure in the doine ik dry gas Chamber 8 is preferably lo :ated in the dome 3 and provided with a perforated top ll through which the gas -enters said Chamber troni said don'ie, and it 'is from the chamber in question that the outlet pipe l0 leads troni the boiler, Vwhereby to carry only extremely hot and dry gas to the engine. The products et combustion from the furnace li rise through the inner shell 2 around the coil and the donie 3,

and are diseharged at 1l. from the top ol the boiler. the Upper end oli said boiler being by preference lined with asbestos or the like as seen at lf2 to shield it against the excessive heat.

Ry means ot' a suitable passage 13, the lower end of the inner shell '.2V communicates with the horizontal easing ll, of the furnace l?, iire-prooled bullies l5 ,being b v preferu ence provided at the sides of the passage as eeen in Figs. il and -l-, said ballles serving to direet the (laine troni the 'furnace burner" 16, against the retort l.

The'I valve in constant eoinniiunication with a blow oli ae will be vclear from Fig. 9, said blow ofi' being` also connected with a 'branch pipe line 29 leading frein the pipe l0 to the injector l ln addition to the valve et' the injector, the pipeline may be provh ed with a eut-oil Valve 3l itl' y desired, and sinnlarly ylaye 3:2 niay be 3,0

The pressure in passing through the Venturi tube i7, creates suction throl'igh the pipe -l-9 to draw the liquid tuel trein the vtank T- and discharge it from the injector through a pipe 51, the lower end ot' said pipeihaving 'branches and a check Valve 53 in advance thereof, Isaid branches hav-l inzg check valves 5l which deliver into the Space/(3 through perforations (Fig. It will thus be seen that by directing),` pressure through the injector7 the boiler may be lilled with the liouid Yfuel whenever required, the level of the tuel in Said boiler from the tank T, it is necessary to apply a suitable pump (not shown) to the connection 59 ot' the pipe 5l, Said eolnwetion havingr a valve (S0 which is closed duringv the ordinary working' of the machine. The boiler haring` been iilled with the liquid fuel, the burner 16 is heated by igniting' an appropriate `tuel iu the pan 18,' and the blow torch 2l is then operated to discharge its nnxture of fuel and air through said burner. lll/hen this mixture is ignited, the flame initially heats the retort eland coil 5, thus geng'as pressure from the liquid 'fuel in the boiler to initially start the engine E when the necessary Valves are openedl l After starting ol the engine, the valve 23 of thelolow torch 21 is cut ofi', since the exhaust gas from thelengine noi7 supplies the burner with gaseous fuel to operate the saine and heat the boiler in the required manner; Although the exhaust- ;g'as is in excess of the amount needed orthe burner 16, it need not be wasted, since opening the valve e0 will conduct such excess gas into the condensing coil 42 of the tank T, thus returning` it to liquid for further use. By en'iployingr` a cheap grade ot liquid fuel, the enlg'inernlay be run with extreme economy, partieuliiri'f in View et the laetthat part o the e limiet. is consumed in the .burner for n' owning' work7 while the remainder thereof is returned te liqui'cljn the tank T.

From the foregoing, taken in connection with the accompanying; drawings, it will be obvious that although the machine is of conn rVU vely simple and. inexpenaiif'e naand in every way desirable. Since probably the best, results` are obtained ltrom the details shown and described. they are b v preterenee t'ollowed` but within the seope et the intention as elaimed. considerable latitude is allowed tor making sueh minor changes as oeeasion may dietate.
